利用氘核加速器的强流快中子源已被提出用于各种应用。为了有助于这种中子源的设计研究，开发了一个高达200 MeV的6，7 Li，9 Be和12，13 C的氘核数据库JENDL/DEU-2020。JENDL/DEU-2020的评估是通过使用代码系统DEURACS进行的，特别关注中子产生数据。为了评估JENDL/DEU-2020，对DEURACS进行了一些修改。库的验证是通过模拟与蒙特卡罗运输计算代码。模拟结果表明，在入射能量为200 MeV的情况下，基于JENDL/DEU-2020的计算结果很好地再现了测量的中子产生数据。新的图书馆预计将作出很大的贡献，不同的设计研究的氘核加速器中子源。
ABSTRACT Intensive fast neutron sources using deuteron accelerators have been proposed for various applications. To contribute to the design study of such neutron sources, a deuteron nuclear data library for 6,7Li, 9Be, and 12,13C up to 200 MeV, JENDL/DEU-2020 is developed. Evaluation of JENDL/DEU-2020 is performed by employing the code system DEURACS with particular attention to neutron production data. Toward the evaluation of JENDL/DEU-2020, some modifications are made to DEURACS. Validation of the library is performed through simulation with the Monte Carlo transport calculation codes. From the simulation, it is shown that calculation results based on JENDL/DEU-2020 reproduce measured neutron production data well in incident energies up to 200 MeV. The new library is expected to make a large contribution to diverse design studies of deuteron accelerator neutron sources.
